Kubernetes Yaml file faster for Deployment and DaemonSet using kubectl

March 24, 2021 comments off

The fastest hack is to create a deployment file using

kubectl create deploy nginx --image=nginx --dry-run -o yaml > nginx-ds.yaml

Now replace the line kind: Deployment with kind: DaemonSet in nginx-ds.yaml and remove the line replicas: 1

However, the following command will give a clean daemonset manifest considering that “apps/v1” is the api used for DaemonSet in your cluster

kubectl create deploy nginx --image=nginx --dry-run -o yaml | \
    sed '/null\|{}\|replicas/d;/status/,$d;s/Deployment/DaemonSet/g' > nginx-ds.yaml
